bomb in tennessee -- >> let me bring in james fox. james fox, you want to jump in. >> that's just ludicrous. >> we seem to be focusing too much just on ar-15s and assault weapons. actually, a small percentage of homicides are committed with assault weapons. >> wait, wait, wait. let me respond to that. because the reason that i've been focused on that, in particular, i'm aware it's a small percentage of the killings in america. but the last four mass shootings in america, aurora, the oregon shopping mall, the terrible case of the firemen lured to their deaths just before christmas, and then sandy hook, all of those have involved an ar-15. it's become the preferred weapon for mass shootings. >> no. >> and the reason is they are killing machines. >> mass shootings are not with assault weapons, actually. >> i said the last four. >> they're with semi-automatic weapons but not assault weapons. and during the assault -- >> what is an assault weapon? >> look at the ban. >> columbine had them when the ban was going on. >> with the greatest of respect to everybody here, especially you, mr.
